subject: Processing Flow Of Gypsum Powder [print this page] Some of the more complex types of mining ore in the mine, the hand-selected separation of fiber plaster, cement plaster, gypsum and a small amount of common anhydrite.
Gypsum calcination process is divided into dry and wet two.
Calcined in dry atmospheric pressure (or water vapor pressure low score) for the heating of gypsum dehydration, and temperature differences to generate -hemihydrate gypsum, -type anhydrous gypsum or burnt gypsum. This product is commonly used in construction plaster, casting plaster cast or pre-products. Wet autoclave calcination in the water vapor pressure, or in low boiling point higher than 100 of the salt solution for heat treatment of the gypsum, the product is -hemihydrate gypsum, gypsum can be used as the basis of special casting material .
Gypsum Powder Processing Flow
-plaster of the production process are generally: broken ore storage all of calcined dehydrated aging mixed grinding and packaging, with the wok when the first milling after calcinations.
Dry gypsum calcining process is: Gypsum shipped from the stope through the store and selected after the first, to ensure continuous and stable quality feed. After a crushing feeding (jaw crusher) to 8cm below, and then broken by the Sec (Crusher) to 2cm below, and then by the bucket elevator into the calcining kiln for calcination. By controlling the temperature of the kiln can be the production of -hemihydrate gypsum, anhydrite and burnt gypsum.
-wet calcining process and the process generally: gypsum raw materials warehouse screening autoclave autoclave machine and drying crushing all of the store and plaster mixed package handling. Hot water production of -hemihydrate gypsum process is:
Equipment commonly used in gypsum crushing- jaw crusher, cone crusher, roll crusher, hammer crusher and so on.
With its high quality products such as Vibrating screenChina cement millOre processing plantHenan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
